-- Mini Cooper R56 --

Hi there, Hopefully one of you guys can help me out here...

I bought new discs and pads to go all around. I fitted 3 of 4 corners without any problems... but the rear Drivers side brake piston won't wind back far enough for me to get the caliper over the new pads. It wound back a little bit, but doesnt want to wind back any further. It still turns fairly easily, but doesn't actually move.

Automotive tire Gas Rim Automotive wheel system Circle

Any ideas on what to do?

Thanks! :)

try it with the fluid reservoir cap off or the bleed screw venting some fluid out perhaps?

I thought the same and took the cap off the fluid reservoir, No joy. I might just remove and re-build the caliper altogether, just thought I'd see if there was an easier fix first.

Thanks for the reply. (y)

make sure you got the pads fitted right way around ,, ie the inner to piston pad has the bigger looking part for the brake wear indicator on it, if try and fit that pad on the outer there are two nipples that make impossible to get the calliper over them ,, if do with force it will wear the pads on a uneven and brake pedal feels spongy

Yeah I've got the pads the right way around, I made sure to double check that. Thanks for the reply (y)

There's enough movement to position the caliper in the correct position, Think it's more the caliper piston not compressing enough. I will double check that though. Thanks.

what you find is callipers over the years of brake fluid not being changed will corrode the screw thread on wind back inside the calliper,, would also say make sure the handbrake cables are backed right off and easy to move etc,
